'roN, a subject of the King of Great Britain, residing at No. 323 Eyre street, South Broken Hill, in the State of New South Wales and Commonwealth 'of Australia,

have invented Improved Means for Suepending and Vertically Adjusting Spring- Rollers and their Attached Window-Blinds, of which the following is a specification. 'This invention has been designed so as to permit of a spring roller and its attached blind being so suspended as to allow 'of its being vertically adjusted and retained in any desired position on the window, so

as to admit of the top sash of the window,

to which my invention is applied, being pulled down in order to ventilate theroom in whichthe said window is situated. The

result is that perfect ventilation of the.

room is secured without any flapping of the blind, while at the same time the occupants of the room are secure from outside observation. A further advantage of my invention is that inthe exent of the blind flying I upward, there is no possibility of jamming,

Y so

as it can easily be pulled down by a person standing on the floor thus avoiding any possibility of accident through having to stand on a chair or the like. Further when an old blind is required to be replaced by a new one, it and-its roller can be pulled down to a convenient height, and the'necessary repairs effected with ease.

y roller fitted with a spindle at each end, which spindles are supported in brackets affixed to the top portion of the frame;

Pivoted to the inner side of the left hand bracket is a pawl which is free to engage with a ratchet on the spindle at that end of the horizontal roller. At each end of said roller is a drum, each end of each drum being fitted with a circumferential flange. To each drum is attached one end of a tape. The other ends'of said tapes are connected to brackets affixed to. the ends of the spring roller carrying the blind, which brackets also carry the said spring roller. A cord is attached to the horizontal rollerv affixed tothe window frame. Bv pulling thiscord the tapes before referred to are wound upon or unwound from the drums at the end of said ho izontalroller thus ra s g or'lowerinvention consists of a horizontal .wmewwmnqwamwn I Application me November 27, ons..- sermim; 2e ,474.
